When the product is empty, you can put the container in your home compost, where it will biodegrade naturally.
If you don’t have a home compost, place it in your general waste. In Denmark, general waste typically goes to incineration, which is fine because the bottle is made from plant-based carbon rather than petroleum. This means it releases carbon that is already part of nature’s cycle, making it much less harmful to the environment.
Currently, as compostable packaging, it is not accepted in the bio-waste bin, but if it ends up there by accident, it will still degrade naturally in landfill, unlike conventional plastics that can sit for hundreds of years.

004
Bioactive Peptides
What it is: Supports microbiome balance while strengthening the skin barrier. Works by promoting beneficial bacteria rather than disrupting the skin ecosystem.
Why it's special: Peptides are more targeted and barrier-supportive than traditional antibacterial actives.
005
Bioactive Emollient
What it does: Lightweight emollient that enhances a product’s skin feel with a silky, non-greasy finish.
Why it’s special: A bio-based alternative to traditional, volatile silicones.
001
BioProtect: Superoxide Dismutase (Enzymes)
What it does: An enzyme-based antioxidant that helps protect against free radicals and oxidative stress, while reducing redness, soothing itching, and supporting skin comfort through its anti-inflammatory properties.
Why it’s special: A gentler, more sustainable alternative to traditional antioxidants like Vitamins C and E and green tea extract, offering antioxidant protection without irritation.
002
Fermented Niacinamide
What it does: Helps to even skin tone and reduces visible imperfections such as hyperpigmentation. Balances sebum.
Why it’s special: The fermentation process lowers the concentration of nicotinic acid, resulting in better tolerated skincare.
003
Multi-Weight, Full-Spectrum Hyaluronic Acid (HA)
What it does: Delivers layered hydration for visible wrinkle reduction and firmer-looking skin.
Why it’s special: It’s more than just regular single-weight hyaluronic acid; it contains multiple molecular weights that work across different layers of the skin to deliver deeper, longer-lasting hydration.

FAQ – Ingredients, Safety and Certifications
How is Bioli Strengthening Serum different from other serums?
What sets the Bioli Strengthening Serum apart is its unique combination of characteristics: a mild formulation with highly effective results that feels silky-smooth on the skin. Like all Bioli products, our serum is produced and packaged to be more sustainable.
The first thing you’ll notice is the texture. Light like a water-based serum but without the thin, watery feel, it goes on with the softness and comfort of oils without the residue, thanks to a bioactive emollient. The result is a rich yet lightweight finish particularly suitable for sensitive skin.
Inside this silky formulation is a bioactive powerhouse, combining multiple bioactive ingredients that strengthen, hydrate, and protect the skin without relying on harsher conventional actives. The formula is based on BioProtect antioxidant enzyme technology, providing the results associated with vitamin C, vitamin E, and green tea extracts, but gentler. These include high antioxidant protection, and anti-inflammatory properties that help reduce redness and itching.
Multi-weight, multi-molecular hyaluronic acid goes beyond conventional single-weight HA to deliver layered hydration, leading to longer-lasting moisture and softer, refreshed skin. Better tolerated than conventional niacinimide, the inclusion of fermented niacinimide helps brighten and even skin tone, reduce hyperpigmentation and blemishes, and balance sebum. Bioactive peptides go beyond collagen support, helping to balance the skin’s microbiome and strengthen the skin barrier by supporting beneficial bacteria.
Rare in skincare, all ingredients are chosen for both effectiveness and low environmental impact with every ingredient being 100% biodegradable. The same applies to the packaging: It’s completely plastic-free and 100% biodegradable, coming in a bottle made from fermented microorganisms that biodegrades without leaving a trace. Outer packaging has also been simplified to a lightweight FSC®-certified paper bag.
The serum is also fragrance-free, AllergyCertified, dermatologically approved – standards we believe should not be exceptional, but expected.
